GM being sued over imploding Bosch fuel pumps in Duramax diesel trucks

Texas-based law firm Hilliard Martinez Gonzalez (HMG) this week filed a class-action lawsuit against General Motors over an alleged issue with Bosch CP4 fuel pumps. The suit claims Bosch designed the CP4 pump to work with European diesel fuel, which is thicker than U.S. diesel. When GM installed that pump in the 6.6-liter Duramax engine used from the 2011 to 2016 model years, the lawsuit claims the thinner U.S. fuel didn't provide enough lubrication, allowing air pockets to form in the fuel pump. That, in turn, allegedly let metal rub against metal inside the pump, causing the pump to eventually disintegrate and "send thousands of metal shards into the fuel injection system and every part of the engine." The Detroit News reported on the most recent lawsuit filed in Michigan's Eastern District Court, but the case is another piece of nationwide legal maneuvering going on since at least last September. Every U.S. truck maker used the Bosch CP4 fuel pump, and HMG originally went after all of them, as well as Bosch. On September 30, 2018, HMG filed a class-action suit in Texas on behalf of eight plaintiffs. The law firm wanted to prosecute the affair under RICO — the Racketeer Influenced and Corrupt Organizations Act — and named 10 defendants: FCA US LLC, FCA North America Holdings, LLC, F/K/A Chrysler Group, Fiat Chrysler Automobiles, N.V., Ford Motor Company, General Motors LLC, Robert Bosch GmbH, Robert Bosch LLC, VM North America, Inc., and VM Motori S.P.A.  The firm filed another suit in Florida on Nov. 2, 2018, against the same 10 defendants, again under the RICO statute, this time on behalf of more than 30 plaintiffs. We don't know how many other suits might have been filed, but the two suits mentioned apparently didn't have legs — the courts dismissed both quickly. So HMG shifted its strategy away from the RICO angle, and focused its efforts on GM, filing suit in California on Nov. 20, 2018. Instead of trying to catch 10 fish with a small net, HMG wants to score one fish with a big net. The results have borne more promise for the plaintiffs. In July this year, a judge in California denied GM's motion to dismiss, noting "the alleged defect is central to the vehicleÂ’s function." This latest suit filed on Aug. 6 in Detroit singles out GM again.  The Bosch CP4 is known to be problematic, however.

IIHS crash tests second F-150 bodystyle

Sometimes, being the king comes with some extra scrutiny. At the urging of Automotive News, the Ford F-150 is the first truck to have multiple cab configurations crash tested by the Insurance Institute for Highway Safety. According to Automotive News, IIHS was preparing to release the crash-test report on the 2015 F-150 after the safety watchdog evaluated the popular, four-door SuperCrew body. However, the agency learned from AN that configuration contained steel bars welded around the front wheels for added protection. Those reinforcements aren't on the other cab variants, and IIHS is now going back to check a SuperCab without the strengthening to check its safety performance, as well. While the added bars might help the SuperCrew score better in the vital but difficult small-overlap front crash test, there's no guarantee that's their sole purpose. As the head of the IIHS crash lab Joe Nolan indicated to Automotive News, if Ford were just trying to beat the system the company could only put the reinforcement on the driver's side where the agency does the small-overlap test. Also, when the National Highway Travel Safety Administration checked the latest F-150, the Feds gave all three cab styles top, five-star overall ratings. Due to the additional testing, IIHS won't have the F-150's scores ready until July, according to Automotive News. Starting next year, the cab variants of other trucks will also starting being crash tested by the agency. Related Video:

From CrabWalks at dawn to post-testing sushi: An inside look at Autoblog’s Tech of the Year Award

TROY, Mich. — On a chilly fall morning, Senior Editor John Snyder rolled into a sleepy suburban park tucked away next to a cemetery a few miles north of Detroit. Driving diagonally — CrabWalking — in the GMC Hummer EV, he made quite the entrance as he maneuvered across the parking lot to the bemusement of Autoblog editors and a few curious park-goers up for their early morning runs.  Snyder got everyoneÂ’s attention, and as we evaluate the latest wave of technologies transforming the automotive industry, pizazz matters. We added "wow factor" to our criteria for the 2022 Autoblog Technology of the Year Award, in keeping with the times. The HummerÂ’s CrabWalk feature might have won, had wowness been the only criteria, but we also scored the technologies on significance and how well they work.  As it was, the Hummer finished a competitive second this year, behind FordÂ’s Onboard Scales and Smart Hitch, which make towing and hauling easier for modern truck owners. The Genesis GV60Â’s Biometrics was within striking distance in third place, bringing the facial recognition and fingerprint tech commonly used in phones to your car. For more on FordÂ’s win — its second straight Autoblog Technology of the Year Award — read Road Test Editor Zac PalmerÂ’s complete recap. Many have asked: Why do Tech of the Year? For Autoblog, itÂ’s been a point of pride for nearly a decade. In the early days it was a way to differentiate ourselves from print magazines, some of which have been giving out car of the year awards since the early days of the Cold War. With Tech of the Year, we seek to highlight the ways experiencing a vehicle is changing. It was true in 2013 and resonates even more as we head into 2023. Cars and transportation have changed more in the past decade than in arguably the previous four. At its most basic experience, driving a 1985 Buick LeSabre with a decent radio and comfy interior was not all that different from driving a 2005 Buick Lacrosse. Just a few years later, many cars had touchscreens, the internet and some means of driver assistance. Ford joins Tesla as the only two-time winner of Tech of the Year. The Blue Oval captured the award last year for its Pro Power Onboard generator. Tesla won in 2014 for its Supercharger network, and the Model S won in 2016, when we briefly gave out a “technology car” of the year award, in addition to honoring a particular feature.
